+# rawdog plugin to truncate article descriptions to N characters.
+# Copyright 2006, 2013 Adam Sampson <ats@offog.org>
+#
+# To use this, give the feed you want to truncate a "truncate" argument:
+# feed 30m http://offog.org/books/feed.rss
+#   truncate 40
+#
+# To truncate all articles, make that a default option for all feeds:
+# feeddefaults
+#   truncate 40
+#
+# You can also remove all HTML tags from the descriptions before truncating
+# them, which'll make the formatting a bit nicer if you're aiming for very
+# short descriptions:
+#   killtags true
